Standardization of the homogeneous mobility shift assay protocol for evaluation of anti-infliximab antibodies. We have developed a non-radio labeled homogeneous mobility shift assay to measure the antibodies-to-infliximab (ATI) and drug levels in serum from patients treated with infliximab (IFX). This method overcomes many of the limitations of the current methods. At week 14 of treatment, patients were randomly assigned (1:1:1) to 3 infliximab maintenance groups: dose increases (2 maximum) in steps of 2.5 mg/kg based on clinical symptoms and biomarker analysis and/or serum infliximab concentrations (dose intensification strategy [DIS]1 group); dose increase from 5 to 10 mg/kg based on the same criteria (DIS2 group); dose increase to 10 mg/kg based on Samples were analysed first by ELISA (Prometheus) and later with a homogenous mobility shift assay (HMSA; Prometheus).

Dehydroepiandrosterone sulfate (DHEA-S), serum or plasma. PROMETHEUS® Anser® VDZ Measures serum vedolizumab (VDZ) levels and antibodies to vedolizumab. PROMETHEUS Serum Infliximab/HACA. Measurement can aid physicians in determining the dose of infliximab and guide infusion intervals. The HACA portion of the test detects human anti-chimeric antibodies (HACA / antibodies to infliximab). Patients that develop HACA may experience infusion reactions and/or a reduced duration of efficacy of infliximab. PROMETHEUS ® Anser ® IFX and PROMETHEUS ® Anser ® ADA are novel laboratory-developed tests that can measure both infliximab or adalimumab and antibody levels from one serum sample.
